Hi, I kept getting the glow light flashing, plug my tool in and got a po122 code. I replaced the pedal position sensor earlier in the year and it’s been fine. It drives ok but keep getting the flashing light and engine management on occasions. I unplugged the connection to the throttle body and found it was full of oil, I cleaned it up and flashing stopped for a few miles but keeps coming back. I took the side off the throttle body and drained the oil as it was full but still having the issue. 
Could this be the electrics faulty because of the oil? Surely it can’t be the pedal as it’s a genuine from skoda

Should also mention it’s a 2.0 tdi cr vrs

That's a failed intake manifold flap 03L 128 063 E

No definitely was the throttle body, the electrics inside were fried. New one fitted and all good
